Mgo board---lots advantages, A1 fireproof; water-resistance; termite-proof; Easy cut; Easy screw; environmental friendly. Mgo board has two kinds formula, one is chloride, another is sulfate. Since the chloride mgo board has the corrosion problem, usually we strongly suggest customer choose sulfate mgo board. However, some customer still insist the chloride mgo board, because they think the bending strength of the sulfate mgo board is weaker.
In this article, i would like to give the detailed explanation.
According to the feedback from a very professional expert, who has been doing research for mgo sulphate for many years. If we analyze or do the test, yes, it's ture. the strength of magnesium sulphate cement is better than magnesium chloride cement, this depends on their own physical properties. But for the mgo sulphate board, the raw materials is not just the mgo sulphate, for mgo chloride board, the raw materials is not just the mgo chloride. It also have some other raw materials. Also, we could do the following step to guarantee the strength of the sulfate mgo board.
1. Increase the density
2. Extend Curing room time
3. Use the short fiber in the raw material
It is easy to let the sulfate mgo board meet the requirement of the bending strength, but nothing can stop the corrosion problem of chloride mgo board.
So we strongly suggest customer choose sulfate mgo board.
